18x-77=(18)/x

18 x - 77 = \frac{18}{x}

x = \frac{9}{2}, x = - \frac{2}{9}

Decimal Notation

x = 4.5, x = - 0.22222 \dots

Solution steps

18 x - 77 = \frac{18}{x}

Multiply both sides by

x

18 x^{2} - 77 x = 18

Solve

18 x^{2} - 77 x = 18 : x = \frac{9}{2}, x = - \frac{2}{9}

x = \frac{9}{2}, x = - \frac{2}{9}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{9}{2}, x = - \frac{2}{9}

20 = \frac{x ^{2}}{75 - x}

x, a = \frac{y}{x - 1}

\frac{5}{x} = 8

(\frac{84}{y} + 2) (y - 1) = 84

\frac{5}{x} = 14
